MEAT-CHOI5PER.

SPECIFICATION forming part f Letters Patent No. 676,347, d t 5111191901- Applioation filed February 21, 1991. Serial No. 48,213. (Nomodel.)

To all whom it may concern.-

Be it known that I, JOSEPH W. WEAVER, a citizen of the United States,residing at Lebanon, in the county of Lebanon and State of Pennsylvania,have invented certain new and useful Improvements in PowerMeat-Choppers; and I do hereby declare the following to be afull, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to meat-choppers, has especial reference to thatclass of meat-choppers driven by power and used to chop large quantitiesof meat, has for its object the'neutralizing of the end thrust of theshaft as far as possible, and consists in certain improvements inconstruction, which will be fully disclosed in the followingspecification and claims.

In the accompanying drawings, which form part of this specification,Figure 1 represents a vertical longitudinal section, partly in sideelevation, of one type of meat-choppers provided with my invention; andFig. 2, a like view, on an enlarged scale, showing the end of the frameto which the ball-bearing is attached.

Reference being had to the drawings and the numerals thereon, 1indicates the frame of a meat-chopper, *2 the casing, 3 the hopper, atthe feed-screw, 5 the knife, 6 the perforated plate at the outer end ofthe casing, and 7 the retaining-ring, all of which may be of anypreferred form of construction.

The frame 1 is provided with an inner shaftjournal bearing 8 and anouterlike bearing 9, in which the shaft 10, with its pulleys 10 10", issupported, and the shaft is provided at its inner end with a shoulder orhead 11, having a socket 12 to receive the pin 13 on the feed-screw, andthe shoulder fills the enlarged bearing 13 with its outer end 14: justfree from the seat 15.

The outer end of the bearing 9 is enlarged at 16 and is internallyscrew=threaded, as shown at 17, to receive the thrust-bearing, whichconsists of a casing 18, having a neck 19, externally screw-threaded at20, and engages the screw thread 17 to connect the thrust-bearing withthe frame of the machine and become a part thereof. Within the easing 18is a disk 21 of less diameter than the interior of the casing to form anoil-chamber 30 to lubricate thethrust'bearing, and said disk is providedwith an annular groove 22, which, in conjunction with the annular groove23 in the disk 24, retainsthe balls 25 in their proper position. Thedisk 21 is free to revolve, and the outer end of the shaft 10 bearsagainst the outer surface of said disk, while the disk 2% is externallyscrew-threaded at 26 and is fixed in the outer end of the casing 18 byconnection with the internal screwthreads 27. As thus constructed thethrust of the shaft 10 is transmitted to the revoluble disk 21, theballs 25, and the fixed disk 24:, and the oil for the chamber 30 issupplied through the opening 28 in disk 24 and is main tained above theballs 25 and the grooves in the disks 21 and 24. g

The bearings 5 and 6 are provided with suitablemeansforlubricatingthesame. (Not shown, as their construction is wellknown.)

Having thus fully described my invention, what I claim is- 1. In a powermeat-chopper, a frame having shaft-bearings; in combination with anantifriction thrust-bearing having a casing provided with a neckengaging one of the hearings on the frame, an oil-chamber within saidcasing, a member forming one of the parts of the thrust-bearing andfixed in the outer end of said casing, a shaft engaging saidthrust-bearing, and a cutter driven by said shaft.

2. In a power meat-chopper, a frame having a shaft-bearing adjacent tothe casing thereof, a like hearing at the outer end of the frameenlarged at its outer end and internally screw-threaded,a cutter, and ashaft connected to said cutter; in combination with an antifrictionthrust-bearing having a casing provided with aneXternally-screw-threaded neck engaging said frame, an oilchamber withinsaid casing, a revoluble disk in and of less diameter than said chamberand provided with an annular groove, a fixed disk at the end of thecasing having a like groove and balls in said grooves.

3. In a power meat-chopper, a frame having shaft-bearings; incombination with an 4. In a power meat-chopper, a frame having ashaft-bearing adjacent to the casing of the chopper and a like hearingat the outer end of the frame; in combination with a shaft having a headat one end and supported in the bearing adjacent to the casing, athrustbearing having a neck and connected to the outer end of the outerbearing for the shaft, a shaft supported in said bearings and in theneck of the casing, and a cutter connected to the head of the shaft.

In testimony whereof I affix my signature in presence of two witnessesJOSEPH W. WEAVER. Witnesses:
